This line seems to showthat the fibril was not continuous with the protox3lasm of the cell. Othersections which have been separated by teasing, show odontoblasts havingtheir side masses of protoplasm drawn away from the fibril which appar-ently has run through it. Some of this protoplasm is left upon the fibril,giving it a ragged appearance as it passes from a canal in the matrix acinusto the separated pulp-tissue, bridging the gap. The pear-shaped cell has perhaps a more important function than theodontoblast proper. It is to supply the life and nourishment to the wholeof the calcified matrix, as the bone-corpuscle within its lacuna supplieslife and nourishment to bone and cementum. One of the strongest arguments, however, in support of the oldertheory that t
